Description

DESCRIPTION

Product and method that allow the manufacture of RFID labels in the field of traceability of textile products, such as in industrial laundries

The invention relates to a method of mounting an electronic radio identification tag. Also refers to an electronic radio identification tag.

Electronic radio identification tags, often designated by the Anglo-Saxon term "RFID tags", RFID being the acronym for the name Radio Frequency Identification, are small objects used to store and restore data, through communication via radio frequencies, usually in relation to a host object. Thus, an electronic radio identification tag is generally placed, ie glued or sewn, for example, or even incorporated, on or into an object. An electronic radio identification tag generally consists of a support or substrate on which a conductive antenna is deposited that is associated, that is, it is connected or coupled electromagnetically to an electronic component. The antenna gives the electronic component a contactless or wireless communication interface that allows it to receive requests that are issued from a transmitter or reader via radio. In return, the electronic component produces a response that is also transmitted through said antenna by radio. These communications generally operate in a frequency band around 900 megahertz (or UHF, short for Ultra High Frequencies) or 13.56 megahertz (or HF, short for High Frequencies) for short-distance communications.

Most electronic tags are said to be passive. In fact, the electrical energy, necessary for the operation of the electronic component of said label, is extracted from the electromagnetic field that is generated by the issuer of a request, when the latter is within range of the communication of the label, that is, to a few tens of centimeters, or even for the most efficient, to a few meters. Other electronic tags are said to be active because they incorporate a power source capable of increasing the power and therefore the range of the tag's emission tenfold.

Electronic labels in particular provide an alternative to beacons or graphic labels, such as bar codes, for example, because they do not require direct reading.

The support that makes up most of the body of an electronic label is generally made up of one or more materials that are adapted to the conditions of use or utilization of the label or of the object on which said label is adhered or integrated. Said support can be rigid or flexible. By way of non-limiting examples, said support may include plastic, cellulosic or textile materials.

The choice of materials, of the components used to make an electronic radio identification tag, as well as the method of mounting said tag, have a great influence on the cost of the tag, the relevance with respect to an application specific, the robustness and durability of said electronic tag.

In the rest of the document, we will describe an example of modality or assembly of an electronic radio identification tag through a preferred and non-limiting application example, in relation to the monitoring of a production flow of an industrial dry cleaner or laundry . In accordance with this application, an electronic tag, usually sewn, is attached to clothing, for example a bed sheet, to track the flow and frequency of washing of said clothing, in a hospital environment or in a hotel industry. Such an electronic label must necessarily be made to adhere easily to such clothing and to withstand, ie remain operative, the particularly harsh environments and/or conditions encountered in cleaning textiles. In this way, the label must be small in volume and not come off or disintegrate during cleaning or ironing of the clothes. In particular, it must resist the attacks of various chemical products present in cleaning products, such as acids, bases or even detergents, and the thermal stresses of drying and mechanical pressing and/or draining.

Many electronic labels, such as those described in document WO2012/1206063, comprise a support or main body that includes a textile material that is selected to be welded by ultrasound, to enclose a conductive or conductive antenna that is coupled to a module of RFID-type radio identification. Said module comprises an electronic component that is connected to a second conductive antenna that is arranged to couple to said first antenna and thus improve the communication range. The latter is responsible for receiving and sending messages to a greater extent. Such a label is the result of a mounting method that requires a large amount of fabric or expensive fabric because said fabric or fabric must be melted under the effect of ultrasound. The textile support consists of a strip folded in half longitudinally to surround the first antenna, as said first antenna is before being woven on said textile support, or even deposited, like the radio identification module, on a layer of a adhesive material that ensures gluing at room temperature of the elements on the support. The two half-strips of fabric are welded together by an ultrasonic welding method, which is particularly complex to industrialize and therefore ultimately expensive. To apply such a tag to a host object, such as clothing, whose path is is going to trace during a dry cleaning method, said label is usually sewn onto said object with the risk of damaging the antenna and/or the module during the sewing of the label.

EP 1 914 671 describes a flexible module for performing near field communication. Such a module is particularly suitable for contactless or dual-interface contact and contactless chip cards.

EP 2 019425 describes an electronic tag comprising an antenna on a substrate receiving a near field communication module. The communication module is encapsulated between two antistatic films to prevent electrostatic discharge during mounting of the module on the substrate.

In order to reduce in particular the volume of fabric necessary to constitute the support of a label as described above, one method, such as that described in document EP2405054, consists in using a textile support comprising a pocket in which the label is inserted. radio identification module of the future label. A conductive antenna, which is arranged to provide communication in the far field, is fixed to the textile support by sewing, laser printing or even through an adhesive that is applied in said pocket. Such a method reduces the amount of tissue needed to make up the label support and avoids requiring the use of ultrasonic welding. However, sealing the pocket is complex so that said pocket surrounds the radio identification module after the latter has been inserted. The economic gain resulting from a reduction in the number of fabrics to make up the body of the label, or even from the selection of materials to lay out the body of the label, is compensated or canceled by implementing a delicate sewing process to make the pocket that houses the module and then close said pocket.

Another technique that is described by document FR3012682 consists, to make the body of the label, in using a textile material in the form of a strip that includes a conductive antenna, before it is embroidered on said textile or printed on it. According to this teaching, a thermosetting adhesive is deposited on said support, at least in an area that partially covers the antenna to ensure future communication by coupling, as said area is provided to receive a radio identification module. Such a method consists in covering the module with a textile strip, by folding the initial strip or by depositing a second strip. The textile support is thus "folded" over the module and the antenna. To enclose the elements, the two textile strips are glued together by hot pressure, which irreversibly triggers the polymerization of the thermosetting adhesive that is placed at the heart of said support. Such a method makes it possible to avoid the use of the previously mentioned ultrasonic welding and dispenses with making a pocket to be closed by sewing. However, such a method reproduces certain drawbacks already mentioned and inherent, in particular in the use of a large number of textile materials to constitute a support envelope for enclosing the antenna and the radio identification module. Such a method of this type also involves the use of a reinforcing element in flexible and elastic material, to give a certain resistance to the electronic label so that the latter naturally recovers its initial shape, that is to say substantially flat, after folding the label. In fact, a label that is made according to the teaching that is taken from the document. FR3012682, which does not include a reinforcing element, would be folded on itself under the action of an ironing or wringing operation of a textile on which the label would be applied. The wireless communication that is granted through the antenna of a label folded on itself would be clearly impaired, at least penalized. Such a reinforcing element, in the form of a tubular element or a silicone plane, for example, which is integrated into the label before the hot-pressing operation to close the envelope of the same, provides sufficient elastic force so that the label covers your sleep configuration. Finally, mounting such a label is always unsatisfactory and efficient. Furthermore, for said electronic tag to be "thermally patchable" or hot positionable on a host object, in particular so as not to alter the integrity of the latter, it is necessary to add an additional adhesive to said tag, which increases the cost of manufacturing the tag. this same.

The invention makes it possible to respond to the drawbacks that arise by means of known solutions by proposing an innovative method of mounting an electronic radio identification tag.

Modular and particularly innovative in design, such a method provides many advantages, among which we can mention:

- the manufacture of a robust and usable electronic radio identification tag within the framework of a wide variety of applications;

- the assembly of a resistant electronic tag that offers, by design, excellent protection of the radio identification module and the antenna;

- Obtaining an electronic label that includes security elements that attest to any malicious attempt to disassemble said label;

- the development of an electronic tag naturally endowed with a shape memory, to preserve its communication capacity without requiring reinforcing elements;

- the provision of a tag facilitates its attachment to any support by avoiding any risk of altering the integrity of the radio identification module and/or the antenna of said electronic tag. To do this, the invention refers to a method of assembling an electronic radio identification tag comprising a radio identification module, a first conductive antenna, a first dielectric support that is arranged to receive said radio identification module and said first conductive antenna, said radio identification module comprising an electronic component that is electrically connected to a second antenna, upon coupling of the second antenna to the first antenna, including said method:

- a preliminary step of depositing on the upper and lower faces of a strip of radio identification modules a layer of a first thermoplastic material having adhesion functions;

- a step for pressing the assembly at a temperature sufficient to activate the first thermoplastic material to ensure lasting cooperation of the layers of the first material on the upper and lower faces of the strip of the radio identification modules;

- a step of cutting the modules that are covered with the first material on the upper and lower faces (10d);

- a step of depositing one of the cut radio identification modules on the upper face of the first support, the latter including the first conductive antenna, said cut radio identification module is positioned in the vicinity of the first conductive antenna;

- a step of depositing on the upper face of the first support a layer of a second thermoplastic material and for pressing the assembly at a temperature sufficient to activate the second thermoplastic material, said layer of second thermoplastic material covering at least partially the first conductive antenna and said cut off radio identification module.

To ensure the correct positioning of the radio identification module before the implementation of the step of depositing, on the upper face of the first support, a layer of a second thermoplastic material, a method according to the invention may advantageously include, before the step of depositing said cut radio identification module on the upper face of the first support, a step for depositing at least in an area of the upper face of the first support, a layer of an adhesive material whose stickiness at room temperature is sufficient to maintaining the position of said cut radio identification module on the first support, said area of the upper face of the first support is intended to receive said cut radio identification module.

As a variant or additionally, such a method may, before the step of depositing said cut radio identification module on the upper face of the first support, a step of depositing on the face of the radio identification module that is intended to cooperate with the upper face of the first support, a layer of an adhesive material whose stickiness at room temperature is sufficient to maintain the position of said cut radio identification module on the first support.

As an additional variant, a method according to the invention may include, before the step of depositing said cut radio identification module on the upper face of the first support, a heating step of the first material that is deposited on the face of said module of identification by cut radius that is intended to cooperate with the upper face of the first support, beyond the melting temperature of said first material.

Before the assembly of an electronic tag as such, a method according to the invention may include a step for assembling the radio identification module. This preliminary stage may consist of:

- depositing or recording on a second dielectric support the second conductive antenna that is arranged to provide near-field electromagnetic communication and an electronic component;

- ensuring electrical cooperation between said second conductive antenna and said electronic component and, - depositing a layer of a protective resin on the exposed faces of said electronic component and said second conductive antenna.

In order to protect the radio identification module from possible impacts or mechanical stresses and also to offer a security function that proves any attempt to fraudulently disassemble an electronic tag that is assembled according to a method according to the invention, the latter may include a stage of depositing, at least on the face that remains exposed of said radio cut identification module, a fibrous mesh that is arranged to be irreparably destructured during an attempt to disassemble the electronic tag that is intended to remove said radio cut identification module from the first support, when said step is implemented before the step of depositing a layer of a second thermoplastic material on the upper face of the first support.

As a variant or additionally, such a method may include a step for recording, at least on the exposed face of said cut radio identification module and on a part of the upper face of the first support that is exposed, a message whose content is irretrievably altered during an attempt to disassemble the electronic tag that is intended to tear off said cut radio identification module from the first support, by said step being implemented before the step of depositing a layer of a second thermoplastic material on the upper face of the first support.

To reduce the number of rejects at the end of the assembly process, a method according to the invention may include a step of electrically testing the radio identification modules and for which the step of depositing said cut radio identification module in the upper part of the face of the first support that is carried out only if said cut radio identification module is operational.

The first support constituting the main body of an electronic tag according to the invention may initially include the first conductive antenna. As a variant, said first support can be deprived of it. In this case, the invention provides that a mounting method may include a preliminary step of depositing the first conductive antenna on the first support or to embroider, print, laminate or weave said first antenna on said first support.

Depending on the desired communication range, in order to reduce the size of the tag, the invention provides that the first conductive antenna carried by the first support may advantageously include one or more loops of a track and/or of a conductive thread.

In order to allow a radio identification module to be deposited on the upper face of the first support, said cut radio identification module includes an internal conductive antenna, without said conductive antenna internal to said module advantageously covering, even if only partially, the first antenna , the latter can be arranged to form one or several loops with a diameter greater than the dimensions of the conductive antenna internal to said cut radio identification module.

According to a preferred embodiment, the first and second thermoplastic materials can be selected from thermoplastic polyurethanes, polyphenylene oxides, polyamides, polyacetates, polyethylenes, polypropylenes, polyolefins or ethylene vinyl acetates.

According to the field of application in which the electronic tag is to be used, the first and second thermoplastic materials can be selected to have respective melting temperatures higher than a certain temperature threshold. This threshold should be higher than the temperatures to which the label will be exposed. The same can be applied to the choice of the material or materials that constitute the first support. The latter may include a material selected from cotton, nylon, viscose, polyester or a synthetic material.

In order to use packaging in the form of a strip that includes a plurality of electronic labels and to facilitate their dissociation, an assembly method according to the invention may include a step of transverse cutting of the first support when the latter is present in the form of a strip, each section being materialized in this way between two previous cutouts that are arranged to include the first conductive antenna and to receive said cut radio identification module.

To increase the protection of the internal elements of an electronic tag that is assembled according to the invention, or even to facilitate the fixing of said tag to a host object, a mounting method may include a step of depositing on the face of the first support opposite to the one intended to receive said radio identification clipping module, a layer of a third thermoplastic material.

The invention advantageously provides that the first and second, or even third, thermoplastic materials may be substantially identical.

The invention also relates to an electronic radio identification tag that includes a support, a first conductive tag antenna, a radio identification module that comprises a dielectric support, a second conductive antenna that is arranged to ensure electromagnetic communication in near field and an electronic component, said electronic component being electrically connected to said second antenna, any exposed face of said electronic component and second conductive antenna being covered by a protective resin, said radio identification module including a layer of a first hot-reactivatable thermoplastic material on an upper face and on a lower face. Said radio identification module being positioned on an upper face of said support, such that the second internal antenna in said radio identification module does not cover said first tag-conductive antenna. Said upper face of the support, that is to say on which the module is placed, includes a layer of a second thermoplastic material, which covers said layer of second thermoplastic material at least partially the first conductive antenna and said radio identification module, having said layer of second thermoplastic material must be hot-rolled to ensure good adhesion with the layer of first thermoplastic material of said module.

To preserve the radio identification module of said tag during its attachment, for example by stitching to a host object, said first conductive tag antenna and said radio identification module they can be arranged mutually on the support so that said module occupies an eccentric position on said support, the latter including a range of a given minimum height, said range partially comprising said first tag antenna but not said radio identification module.

Figure 1 illustrates a preferred example of implementation of a production line or machine for assembling and/or adapting a radio identification module 10 according to the invention. Said Figure 1 will be described in relation to Figure 4 which illustrates, for its part, a global sequence of a method 100 of mounting an electronic radio identification tag incorporating said module 10.

The assembly as such of an electronic tag 1 will be described, for its part, in relation to Figures 2 and 3, according to the configuration of the electronic tag to be produced.

In conjunction with Figures 1, 1A, 1B and 4, a first step of a mounting method 100 according to the invention consists of mounting or adapting a radio identification module 10 which is intended to cooperate by coupling with a conductive antenna, to the said antenna being arranged to provide communication in the far field, that is, at a distance of a few meters.

As mentioned above, such a module 10 mainly comprises a dielectric support 13, such as an epoxy, a polyamide or also a polyethylene terephthalate, commonly known by the Anglo-Saxon abbreviation "PET" for polyethylene terephthalate. Said support is packaged in the form of a strip that is driven in translation by means of an unwinder D1 that is associated with a guide G1, such as a motorized roller. A mounting method 100 according to the invention may include a first step 120 for assembling a radio identification module 10. A preliminary stage 120 of this type advantageously consists of depositing, engraving or printing 121 a conductive antenna 12 on one face 13u, which is called the upper face, of the support 13. Said stage 120 also consists of depositing an electronic component or microcontroller 11 on said upper face 13u of the support 13. In order for said electronic component 11 to be able to communicate by coupling with a third dipole, said component 11 is electrically connected 122 to the antenna 12. Such an operation 122 can result from a connection of contact ranges of the component 11 to one or more tracks or turns of the antenna 12 by means of one or more conductor cables 16, as shown in Figure 1. As a variant, certain electronic components 11 have an active face. Said component is placed, face active against the antenna 12, as this operation directly ensures an electrical connection. This is then called the "flip chip" method according to Anglo-Saxon terminology. To protect the component 11, any cables 16 and antenna 12, step 120 may consist of covering said elements 11, 12, 16 that are exposed with a non-conductive protective resin 14. "Exposed element" or "exposed face of an element" means any element or part thereof that is not in direct contact with a third element.

The component 11, the antenna 12 and possibly the cables 16 are thus covered by said protective resin. This is cured, for example, by ultraviolet polymerization, by thermal crosslinking or by any other technique. Step 120, as described in relation to Figure 4, corresponds to a method of assembly of a conventional and known radio identification module. On the other hand, the invention provides for an additional step 130 of depositing on the upper 10u and lower 10d faces of the radio identification module 10, a layer of a first thermoplastic material TP1.

Thus, at the end of this step 130, a radio identification module 10 according to the invention has an upper face 10u' and a lower face 10d' including such a layer of the first thermoplastic material TP1.

By way of non-limiting example, the TP1 material can consist of a thermoplastic polyurethane, also known by the acronym TPU. As a variant, said thermoplastic material TP1 can be selected from thermoplastic polyurethanes, polyphenylene oxides, polyamides, polyacetates, polyethylenes, polypropylenes, polyolefins or vinyl ethylene acetates, which are advantageously packaged in the form of sheets.

More generally, in the sense of the invention, "thermoplastic material" means any material or polymer capable of being repeatedly activated under the effect of an increase in temperature, when said temperature exceeds a certain melting temperature. Activation of said material shows a change of state from the solid state (at room temperature) to a viscous liquid state. In this way, when a melting temperature of the material is reached or exceeded, the latter softens and can be easily shaped. It hardens on cooling. Thus, in the sense of the invention and throughout the document, said thermoplastic material is advantageously reactivatable when hot. Such material differs from a thermosetting material that can only be used once by polymerization. In addition, such a thermoplastic material includes adhesion functions that, when the latter is reactivated, that is, heated beyond the melting temperature of said material, allows the radio identification module or more generally the label to be repositioned. radio identification electronics on a carrier or any host object.

The invention further provides that the thickness of the layer of the first thermoplastic material TP1 that is deposited on the faces 10u and 10d is from fifty to five hundred micrometers, typically two hundred micrometers. In fact, such a thickness makes it possible to have a radio identification module that has interesting elasticity properties, while retaining a possible flexibility. The active elements, that is to say the component 11 and the antenna 12, are thus protected against the appearance of impacts, as the latter are absorbed by the thermoplastic material TP1 or the physicochemical attacks of the environment of the label. To manufacture a module 10 of this type, Figure 1 describes an example of a production line or machine embodiment according to which a second unwinder ^d 2, associated with the guide means G1, drives in translation a coil of the first thermoplastic material TP1 to deposit a layer thereof on the upper face 10u of the radio identification module 10. Likewise, a third unwinder D3, which is associated with a guide G3, can be used to drive in translation a coil of first thermoplastic material TP1 to deposit it in a layer on the lower face 10d of said radio identification module 10. A hot laminating or pressing step 130a, that is to say at a temperature higher than the melting temperature of the first thermoplastic material TP1, ensures lasting cooperation of the upper and lower layers of the first material TP1 on the upper 10u and lower 10d faces of the module. . Such a pressing operation 130a can be used by means of a pair R1 of rollers, parallel to each other, which ensure a pressing function of the assembly when the latter is pulled between said rollers, so that the adhesion of the two layers of material TP1 is durable. . Alternatively, parallel pressers, whose temperature, pressing time and pressure can be adjusted as needed, can be used instead of said rollers R1.

Figure 1 also describes an example of a modality for the deposition of a layer of thermoplastic material TP1 on the respective upper and lower faces of several modules simultaneously. As shown in Figure 1A, the radio identification modules 10 can be advantageously positioned on a support in the form of a thirty-five millimeter wide strip. Such a configuration allows said modules 10 to be positioned in columns of three modules transverse to the longitudinal axis of the strip. After an application 130 of the thermoplastic material TP1, the radio identification modules are trimmed 132 and isolated from each other.

A method 100 according to the invention provides, before the assembly of an electronic tag as such, a step 133 to electrically test the correct operation of the radio identification modules that are covered by the thermoplastic material TP1. Such an operation 133 may be implemented before or after disassociation 132 of said modules 10. Faulty modules are rejected, a situation which is illustrated by link 133-n in Figure 4. Otherwise, a situation which is illustrated by the link 133-y in Figure 4, the module is operational and can be used in the context of post-mounting an electronic tag. This test step 133 can also allow initializing or updating the content of certain memories of the electronic component that is included in a radio identification module considered to be operational.

In addition, an assembly method 100 according to the invention may include, after the deposition 130 of the layer of thermoplastic material TP1, an optional step 131 that is intended to deposit on a lower or upper face of the module 10, that is, one of the faces of the radio identification module 10 intended to cooperate with the upper face 30u of a support 30 constituting an electronic tag (we will study this assembly step later in relation to Figures 2 and 3), a layer of a adhesive material A whose stickiness at room temperature is sufficient to maintain the future position of the radio identification module 10 on said support 30. In the example described in relation to Figure 1B, said adhesive A is deposited on the lower face 10d' of the radio identification module 10. Said adhesive A could be easily deposited as a variant or additionally on the upper face 10u'. Such a material can advantageously be selected from pressure sensitive or activatable adhesives (or known by the acronym "PSA" or the Anglo-Saxon name "Pressure Sensitive Adhesive").

Like the layers of thermoplastic material TP1, the adhesive A can be deposited on one of the faces 10d' or 10u' of a radio identification module 10 by means of an unwinder D4, which is associated with a guide G4, by activating a strip of adhesive material A that is applied by means of a pressure roller or a press R1. Before the operation 131 to deposit the adhesive A, a method 100 according to the invention may include an advantageous step 130b to accelerate the return to room temperature of the module 10, said step 130b not being shown in Figure 4.

As shown in Figure 1B, at the end of the implementation of the steps described above, one or more radio identification modules are produced, each of which is adapted according to the invention. More precisely, such module 10 comprises a dielectric support 13, a conductive antenna 12 that is arranged to provide near field electromagnetic communication and an electronic component 11. Said electronic component 11 is electrically connected to said conductive antenna 12. Any exposed face of said electronic component 11 and of the conductive antenna 12 is covered by a dielectric resin 14. Said upper 10u' and lower 10d' faces of said module 10 include a layer of a thermoplastic material TP1, or even for at least one of them, a layer outside of an adhesive A. We can mention that steps 121, 122 and 123 can be optional, if the radio identification modules 10 are already assembled. Therefore, the invention consists in adapting said modules 10 so that their upper 10u' and lower 10d' faces each include a layer of a thermoplastic material TP1, or even so that one of the lower 10d' or upper 10u' faces includes furthermore an outer layer of an adhesive A which can be activated by pressure at room temperature.

Let us now describe, together with Figures 2, 2A, 2B, 2C and 4, the steps of a first example of a method of mounting an electronic tag as such, according to the invention. According to said Figures 2, 2A, 2B and 2C, the electronic tag to be produced includes a far-field antenna 20 to ensure contactless communication with a third-party device, distant from several tens of centimeters to several meters. To reduce its bulk, the substantially flat conducting dipole, which is formed by said antenna, advantageously includes a plurality of loops 20L. Figure 2A describes a preferred example of a support 30 in the form of a strip to constitute the body of an electronic label according to the invention. As shown in Figure 2, said strip 30 can be driven in traction by an unwinder D5 associated with a guide G5. The support 30 can include a material that can be selected from cotton, nylon, viscose, a polyester or a synthetic material, such as, by way of non-limiting example, Tyvek (registered trademark), according to the specific field of application to exploit the future label 1. Figure 2A also describes a particular arrangement of a conductive antenna 20. Unlike known techniques according to which said antenna generally describes a meander or a sinusoid, a conductive antenna 20, depending on the modality described by Figure 2A, depicts a plurality of loops 20L whose respective diameter(s) are chosen to be greater than the dimensions (widths, lengths, or even diameter) of a radio identification module. Said loop diameter 20L will be more precisely determined to be greater than the dimensions of the conductive antenna internal to said radio identification module, that is, the antenna 12 of the module 10 which is described in relation to Figure 1B. In this way, as we will see later, said antenna 20 configuration allows a radio identification module to be positioned in the vicinity of said antenna, thereby ensuring excellent coupling and avoiding any overlapping of the antenna 20, in particular by means of the internal antenna of said radio identification module capable of causing a partial rupture of the antenna 20, or even of the module 10 during a subsequent stage of hot pressing of the assembly. Any other configuration of the antenna 20, whose arrangement would allow such positioning of a radio identification module 10, that is to say that it has a minimum distance d of the order of half a millimeter between the antenna 12 internal to said module 10 and the antenna 20 could be used , as described by way of example in Figure 3D in relation to a second example of mounting a mini label 1 according to the invention.

A support 30 can already include one or several conductive antennas 20. As a variant, as indicated in Figure 4, a mounting method 100 according to the invention can include a step 110 for the modality of said support 30. In this way , a first step 111 may consist of depositing a conductive antenna 20 on the support 30. Such an antenna may consist of a plurality of conductive wires. In this case, said threads can be embroidered or woven on said support 30. As a variant, said antenna 20 can be printed by any known technique or deposited by lamination and therefore consists of a conductive track.

As indicated by the preferred example described in relation to Figure 2A and Figure 4, a method 100 according to the invention may include a step 112 of cutting transversely to the support 30. Each section 30s is thus materialized between two cuts 30c that are arranged to include the conductive antenna 20 and to receive a radio identification module 10. The support 30 has a face that we will name upper face 30u and a face opposite to the previous one that we will name lower face 30d.

As shown in Figure 2B, a mounting method 100 according to the invention includes a step 140 of depositing, on the upper face 30u of the support 30, a radio identification module 10, before it is adapted according to the technique that it is described above in relation to Figures 1A, 1B and 1. Said module 10 thus includes a layer of a first thermoplastic material TP1 on its lower 10d' and upper 10u' faces. The invention provides that the positioning of said radio identification module 10 can be precisely determined, for example, by means of a vision system, which is symbolized in Figure 2B by a video sensor C, so that the internal antenna of said module radio identification tag 10 does not cover the conductive antenna 20, such as the advantageous embodiment form of a small format tag 1 which is described in relation to Figure 3D. In this way, said vision system makes it possible to control the coordinates of the radio identification module 10 in the plane of the support 30. Alternatively, any other technique that allows a radio identification module 10 to be positioned correctly and precisely on the support 30 could be used. support 30. According to the embodiment described by Figure 2B, such a module 10 occupies, once it is deposited on said support 30, a substantially central position within a cut section 30s. As a variant, said module could be positioned within another loop 20L of said antenna 20 and thus occupy a more eccentric position within the tag. Furthermore, Figure 2B describes an advantageous example of a production and/or assembly line so that a plurality of radio identification modules, in this case three by three, are positioned simultaneously and respectively on three consecutive sections 30s of support 30 .

To maintain the position of a radio identification module 10 during the movement of the support 30, the invention provides for the advantageous use of an adhesive A whose tackiness at room temperature is sufficient to maintain the position of said radio identification module 10.

We previously studied an embodiment of a method 100 according to which an optional step 131 consists of depositing on the face 10u' or 10d' that is intended to be in contact with the support 30, a layer of said adhesive A. In this case , during placement 140 of such a radio identification module on support 30, said module is held in position under the action of said adhesive A.

The invention provides a first variant or a first complement according to which said adhesive A, for example, which is selected from pressure sensitive or activatable adhesives (or which are known by the acronym "PSA" or the Anglo-Saxon name "Adhesive pressure-sensitive") can be placed at least in an area of the upper face 30u of the support 30 before placing a radio identification module 10. According to this embodiment which is described in relation to Figure 2B (not shown in Figure 2), a layer of an adhesive material A is deposited from an unwinder, on the central loops 20L of the respective antennas 20 of the sections 30s of the support 30. As a variant, said adhesive A could be deposited on the entire upper face 30u of the support 30 or on other portions of said face 30u corresponding to sections of antenna 20 other than those described by the central loops 20L, as shown described by way of example in Figure 2B, if the radio identification module or modules 10 are not intended to occupy a substantially central position.

According to a third embodiment, the invention provides that it is not necessarily possible to use such an adhesive A. In fact, the thermoplastic material TP1, which is deposited beforehand in a layer on the radio identification module, can be heated beyond the temperature melting of said material TP1, just before coming into contact with the upper face of support 30. Said module 10 is then placed and then hot-pressed onto support 30. In the absence of adhesive A, thermoplastic material TP1 provides a adhesion or adherence function, once said thermoplastic material TP1 is heated beyond the melting temperature of said material TP1, and in this way allows avoiding the absence of additional adhesive as such.

A mounting method 100 according to the invention, such as that described by way of example in relation to Figures 2C, 2 and 4, may include, after a radio identification module has to be positioned on the support 30, a step 142 of depositing at least on the exposed face 10u' of said radio identification module 10, a fibrous mesh 50. The latter is advantageously designed to be irreparably deconstructed during a malicious attempt to disassemble the electronic tag 1, which is intended to tear said radio identification module 10 from the first support 30. As shown in Figure 2, said mesh can be unwound from a D6 unwinder and be guided by a G6 roller. To optimize the amount of mesh required, the latter can be packaged in the form of a strip with a width substantially greater than that of the radio identification module. Beyond a security function that is intended to reveal an attempt to disassemble a tag, the presence of said mesh can contribute to the protection of the electronic component that is housed by the radio identification module against possible impacts or mechanical stresses .

As a variant or additionally, to provide an additional security element that is intended to attest to a fraud attempt, the invention provides that a method 100 may include a step 143 to register, at least on the exposed face of the identification module 10 by radio and on a part of the upper face 30u of the first support 30 that is exposed, a message 60, the content of which is irretrievably altered during an attempt to disassemble the electronic label, which is intended to start said identification module 10 by radio , the first support 30. Said message can be textual, for example, "void if deleted" according to an Anglo-Saxon or figurative terminology (including a logo), or even mixed.

Whether a mesh 50 and/or a message 60 is deposited and/or printed respectively, a method 100 includes an essential step that is intended to deposit on the upper face 30u of the first support 30 a layer of a second thermoplastic material TP2, said layer by at least partially covering the first conductive antenna 20 and the radio identification module 10. Such a layer can be deposited, as shown in Figure 2 by way of example, under the action of an unwinder D7 of a strip of thermoplastic material . Step 150 also consists of hot pressing, that is to say at a temperature higher than the melting temperature of the thermoplastic material TP2, the assembly to ensure lasting cooperation of the layer of thermoplastic material TP2 on the upper face 30u of the support 30. Such a pressing operation can be carried out by means of a pair R2 of rollers parallel to each other, by ensuring a pressing function of the assembly or of the assembly when the latter is pulled between said rollers, so that the adherence of the two layers of material TP2 is durable. Alternatively, parallel pressers, whose temperature, pressing time and pressure can be adjusted as needed, can be used instead of said rollers R2.

Like the first material TP1 used to adapt a radio identification module, the thermoplastic material TP2 can be selected from thermoplastic polyurethanes, polyphenylene oxides, polyamides, polyacetates, polyethylenes, polypropylenes, polyolefins or ethylene-vinyl acetates, advantageously They are packaged in the form of films. According to the specific field of application, the choice of TP2 material will depend on the melting temperature beyond which said material can be activated once or several times. For the field of electronic labels for industrial laundries, a thermoplastic polyurethane whose melting temperature will be greater than 180°C will advantageously be preferred.

Thanks to the use of said thermoplastic material TP2, an electronic label produced according to the invention has interesting properties of elasticity, while retaining the possible flexibility. In a certain way, it naturally has a shape memory, which does not require the use of an additional reinforcing element. The TP2 material, as well as the TP1 material, give the body of the label a very good hold in such a way that said label naturally covers its initial shape, that is to say substantially flat, after folding the label. Therefore, the quality of the wireless communication that is imparted by the antenna 20 is preserved.

A mounting method 100 can now be completed. According to Figure 2, a plurality of electronic tags are packaged in this manner in the form of a strip. However, said method 100 may include additional steps. A first step, not shown in Figure 4, may consist of electrically testing the operation of each label that is produced. An inoperable tag can be marked, for example by inkjet, for identification and disposal. Such a test stage can also make it possible to update certain memories of the electronic component of the radio identification module of each tag that is produced. This operational label discrimination stage thus allows managing and controlling the sequence of serial numbers or other unique references that are respectively associated with the labels and ensure their consistency with an optional stage of said graphic printing method 100, stage that is also not shown in Figure 4, to allow each label to be personalized, or even to visually record said serial number or unique reference.

The strip advantageously including a plurality of labels, resulting from an assembly method 100 that is described in relation to Figure 2, may also include a step 160 for cutting said strip, for separating the labels from each other, or even for packaging them. each in a blister. As a variant, in particular if the support 30 is not cut beforehand, said step 160 may consist of cutting said strip that includes the labels that are produced in order to make the latter easily dissociable from each other, by maintaining a strip packaging mode that includes each a plurality of labels.

A method 100 may further include a step 151 of depositing on the lower face 30d of the support 30, that is to say the face opposite to the one 30u that houses a radio identification module 10, a layer of a third thermoplastic material TP3. At the end of this stage, the front but also the back of a substantially flat electronic label can be covered with thermoplastic material. For the reasons mentioned above, said TP3 material may advantageously be selected to be substantially similar to the first and/or second thermoplastic materials TP2 and/or TP1.

Whether or not this last step 151 is carried out, we can also mention that the use of the layer of material TP2, in particular if it is carried out on the entire upper face of the support 30, substantially reduces or eliminates all relief at the level of the label. , which in this way facilitates the later application of said label 1 in a host object. This application can be done by hot pressing. Activation of the TP2 thermoplastic material, followed by cooling, ensures long-lasting positioning of the label.

Figures 3A, 3B and 3 describe a second example of a method of mounting an electronic tag according to the invention. According to this variant, the format of a label that is obtained is smaller than that of a electronic tag that is assembled according to the method described above in relation to Figures 2 and 2A.

In fact, as the example of Figure 3A indicates, the support 30 consists of a strip of lesser width, possibly cut. Support 30 includes an antenna 20 including, by way of example, a single loop 20L. In this way, the dipole that is formed by the antenna 20 is therefore shorter than that of a tag, as assembled with an antenna 20 that includes a plurality of loops 20L, as indicated in Figure 2A.

The communication range that is provided by the antenna 20 of the example of Figure 3A, or even of Figure 3D, is therefore less but sufficient to serve as a relay between the identification module 10 that is coupled with said antenna 20 and a third antenna 2, which is sewn for example on a host object 3 such as a cloth and passed through the antenna 20, as shown in Figure 3c. A mounting method 100, such as that described in connection with Figures 3A, 3B and 3, is close to or similar to that described above. We can see that it includes a step 140 of depositing, on the upper face 30u of the support 30, a radio identification module 10 before it is adapted according to the technique described above in relation to Figures 1A, 1B and 1. In this way, a module includes a layer of a first thermoplastic material TP1 on its lower 10d' and upper 10u' faces. The invention foresees that the positioning of said radio identification module 10 is precisely determined, for example, by means of a vision system, which is symbolized in figure 3B by a video sensor C, so that the internal antenna of said module identification module 10 does not cover the conductive antenna 20. In this way, said vision system allows to control the coordinates of the radio identification module 10 in the plane of the support 30. Alternatively, any other technique could be used that allows correct positioning and precisely a radio identification module 10 on the support 30. Unlike the substantially central position of a module that is deposited according to the example of Figure 2B, a radio identification module 10 is deposited, according to this second embodiment, substantially eccentric within an optionally cut section 30s. As shown by way of example in Figure 3D, an eccentric positioning of the radio identification module 10 inside an electronic tag 1 according to the invention allows, at the end of the assembly process, to have a main body of electronic tag 1 that includes an increased range P, for example, with a height h of four to five millimeters or more, partially comprising the antenna 20 but not including the radio identification module 10. Such an assembly process 100 allows minimizing the size of an electronic tag 1 while retaining a great facility to sew, for example, as shown in Figure 3C, an antenna 2 that passes through the antenna 20 of said "mini tag," without risk of altering the latter's radio identification module In this way, said antenna 2 performs the respective functions of improving the electromagnetic performance and of fixing the mini tag on the host object 3. Such an arrangement of electronic tag 1, which is described in relation to Figure 3D which illustrates an example of a tag that is assembled according to the invention, allows to present a configuration of an antenna 20 different from that illustrated by Figure 3A, but which is arranged so that they remain in nearby parts, that is to say a distance d of the order of half a millimeter, from the internal antenna 12 to the radio identification module of the tag, without said antenna 20 being covered by said internal antenna 12. Such an arrangement ensures excellent coupling and minimizes the risk of breakage during the pressing phases. In this way, regardless of the materials used to constitute said electronic tag 1, such an arrangement according to which the tag includes a range P that preserves the radio identification module is particularly innovative and avoids any destruction of the radio identification module during fixing, in particular when sewing, of the label of the host object 3.

Furthermore, Figure 3B describes an advantageous example of a production and/or assembly line for which a plurality of radio identification modules, in this case three by three, are positioned simultaneously and respectively on three consecutive sections 30s of support 30 .

Like the example of a mounting method described above in relation to Figure 2, a method according to Figure 3 provides for the advantageous use of an adhesive A whose tackiness at room temperature is sufficient to maintain the position of a radio identification module 10 on support 30. As a variant, the layer of thermoplastic material TP1, which is deposited before on the radio identification module, can be heated beyond the melting temperature of said material TP1, just before placing said radio identification module on the upper face of the support 30. Then, said module 10 is placed and then hot-pressed on the support 30.

A mounting method 100 according to the invention and like the one described by way of example in relation to Figures 3 and 4, may include, after a radio identification module has to be positioned on the support 30, a step 142 of deposit at least on the upper face that remains exposed of said radio identification module 10, a fibrous mesh 50 that is advantageously arranged to be irreparably dismantled during a malicious attempt to disassemble the electronic tag 1, which is intended to tear said identification module radio identification 10 of the first support 30. Such a method 100 could further include a step 143 for recording, at least on the exposed face of the radio identification module 10 and on a part of the upper face 30u of the first support 30 that remains exposed , a message 60, the content of which is irreparably damaged during an attempt to disassemble the electronic tag that is intended to boot said radio identification module 10 of the first support 30. Said message can be textual, for example, "void if deleted" according to Anglo-Saxon terminology or figurative, including a logo, or even mixed.

However, these steps are optional. By way of simplification, and to illustrate an alternative modality according to which the use of means that attest to an attempt to alter the integrity of an electronic label is not required, Figure 3 describes a mounting method that does not include steps 142 and/or 143.

On the other hand, a method 100 according to Figure 3 includes an essential step 150 of depositing on the upper face 30u of the first support 30 a layer of a second thermoplastic material TP2, said layer covering at least the first conductive antenna 20 and the radio identification module 10. Given the small surface of the electronic antenna that is produced, said layer of thermoplastic material TP2 advantageously covers the entire surface of the support 30. Such a layer can be deposited, as shown in Figure 3 as a example, under the action of an unwinder D7 of a strip of thermoplastic material. Step 150 also consists of hot pressing, that is to say at a temperature higher than the melting temperature of the thermoplastic material TP2, the assembly to ensure lasting cooperation of the layer of thermoplastic material TP2 on the upper face 30u of the support 30. Such a pressing operation can be carried out by means of a pair R2 of rollers, parallel to each other, by ensuring a pressing function of the assembly when the latter is pulled between said rollers, so that the adherence of the two layers of material TP2 is durable.

The second thermoplastic material TP2 can be selected from thermoplastic polyurethanes, polyphenylene oxides, polyamides, polyacetates, polyethylenes, polypropylenes, polyolefins or vinyl ethylene acetates, which are advantageously packaged in the form of films.

The exemplary mounting method 100 described in connection with Figure 3 can now be completed. In this manner, a plurality of electronic tags can be packaged in the form of a strip. However, said method 100 may include additional steps. A first stage may consist of electrically testing the operation of each label that is produced. An electronic tag deemed non-operational may be marked, for example, by ink-jet type printing, for disposal. Such a test stage can also make it possible to update certain memories of the electronic component of the radio identification module of each tag that is produced. This operational label discrimination stage thus allows managing and controlling the sequence of serial numbers or other unique references that are respectively associated with the labels and ensure their consistency with an optional stage of said graphic printing method 100, stage that is also not shown in Figure 4, to allow each label to be personalized, or even to visually record said serial number or unique reference. Such a step can also make it possible to graphically materialize, for example by printing a mark, the possible seam range P within which the radio identification module is kept.

A strip of labels resulting from a mounting method 100 that is described in connection with Figure 3 may also include a step 160 for cutting said strip, for separating the labels from one another, or even for packaging each one in a blister pack. As a variant, in particular if the support 30 is not cut beforehand, said step 160 may consist of cutting said strip that includes the labels that are produced in order to make the latter easily dissociable from each other, by maintaining a strip packaging mode that includes each a plurality of labels.

According to this example that is described in relation to Figure 3, a method 100 does not include a step of depositing on the face 30d of the support 30, that is, the face opposite that 30u that houses an identification module 10 by radio a layer of a third thermoplastic material TP3. However, this stage could also be carried out. Figures 2 and 3 thus describe examples of a radio identification tag mounting method that is particularly innovative and adaptable according to the requirements of the field of application. The labels that are produced can be of different dimensions, as shown in Figures 2A and 3A, and include antennas that allow them to communicate directly with a remote reader, which are coupled or even connected to a third antenna that is positioned on the a host object. The use of thermoplastic materials gives the labels according to the invention, whatever their layout, great ease of positioning, or even repositioning, as well as unparalleled reliability. They are specially adapted for the field of industrial laundries, demanding and severe in terms of operation given the high temperatures and the chemistry to which these labels are exposed.

However, such a method cannot be limited to the production of electronic labels for this field only. The materials that are used can be advantageously chosen to meet the conditions and limitations that are imposed by any other application.
